The article is devoted to the main patterns of tectonic development in the Middle Ob for the period from the tops of the middle Jurassic to the Eocene. It is shown that during this period of time in the tectonic development of the territory there were periods of quiet sedimentation and very active tectonic activity. In the history of the tectonic development of the Middle Ob four major stages are distinguished: two is quiet (the Jurassic and the Upper Cretaceous) and two are very active with large-scale multidirectional movements that led to a significant increase in the amplitudes of the structures (from the Cretaceous to the roof of the Cenomanian century).The article describes the methodology of the correlation analysis used in the study of the history of tectonic development in the territory.

Modern detailed stratigraphical studies have demonstrated very clearly the long and involved tectonic history of the majority of the main structural units of England. It has been proved that, in certain areas, the thickness and the lithology of the sediments were partly determined by repeated pene-contemporaneous folding along definite axes, and thus it has been possible to trace the gradual growth of some of the main fold lines of the country. The Weald is typical of these areas, whose structure, at first sight simple enough, reveals on closer study much complexity of the minor folding and faulting and also gives evidence of long continued movement along certain lines; movement contemporaneous with the deposition of beds which were involved in the final crescendo of tectonic activity.

The territory of Armenia, although relatively small, is geologically and tectonically complex. Its complexity is not only due to a dense network of faults. It results from a complicated history of tectonic development including several phases of mountain formation and planation, and the extensive development of fold-block, tectonic and magmatic processes. An important scientific task is identification of earthquake-prone structural blocks by analysing seismotectonic data on geotectonic zones in Armenia. This article describes the seismotectonic analysis of geological and geophysical data on the Viraayots-Karabakh zone.We used a wide spectrum of modern tectonic-geomorphological indices and GIS technologies in order to assess the neotectonic (Neogene – Quaternary) activity of the main block units of the study area and to classify the block units by their tectonic activity levels. Tectonics of the study area is contrasting, and many tectonically active blocks are in the immediate neighbourhood with passive blocks.Based on the records of seismic events of various magnitudes and historic earthquake data, we analysed modern seismicity of the block units. For each block, a quantitative analysis of its total seismic energy release was performed, and relationships between the released seismic energy values and the number of recorded earthquakes were analyzed. Based on such analysis, we identify a group of blocks wherein the total released seismic energy values are high, but the numbers of seismic events recorded in these blocks are rather limited. In the context of block tectonic activity, analysing these data makes it possible to detect the blocks with the highest probability of the occurrence of strong earthquakes.

Geomorphological and geological features of the eastern part of Lviv have been analyzed. A new, extremely picturesque and informative tourist, recreational and geo-educational route has been developed, namely “Chatovi Rocks – Vynnykivske Lake –Medova Pechera”, which forms an extension of “Vysokyi Zamok – Chatovi rocks” tourist route. Picturesque relief, exposure of sediments of various ages and genesis, as well as rich archeological monuments occurring along the routecan perform educational, educational, cognitive, ecological, and aesthetic functions. Archaeological memorials, little known to the general public, are extremely valuable, too, because they illustrate the history of populating the city of Lviv and its neighborhood. Mostly inanimate objects located along the route are well accessible for exploration; however, today they are not very popular among Lviv residents. This is primarily due to the lack of proper infrastructure – marked trails, information stands, etc. Anthropogenic impact on the objects located along the proposed route is extremely diverse and large-scale. Some sites (such as Chatovi Rocks and Medova Pechera) are affected heavily, as they are actively used for hiking, mountaineering, etc. Others (for example, Zhupan and Lysivka archeological monuments) virtually do not experience it. The monuments of Mlynivtsi I and II are exposed to the greatest threat, up to complete destruction. They are endangered due to the extensive construction of a new sports and recreation complex, deployed around Vynnykivsky Lake. The refore, the condition of these facilities needs to be monitored continuously. On the other hand, the said complex will open up new prospects for the use of picturesque relief, complex geomorphological and geological structure of the eastern part of Lviv in the future recreational and geo-educational activities. There is no doubt that the new center of attraction, created by the sports and recreation complex, will increase the attendance of Vynnykivsky Forest Park. Therefore, the need to establish appropriate tourist, recreational, geo-educational infrastructure along “Chatovi Rocks – Vynnykivske Lake – Medova Pechera” route is obvious today. Key words: nature-learning and geo-archeological route; Upper Cretaceous marls; Neogene sands and sandstones; woods, travertines; archeological monuments.

Abstract The study of certain outcrops in the Subbetic zone indicates diapirism of Triassic strata beginning as early as the Turonian (upper Cretaceous). These movements of the evaporitic strata of the Triassic have had an important influence on the tectonic development of the western Mediterranean. Although deformation of the diapirs by tangential tectonic activity has made them difficult to recognize, they occur on both sides of the western Mediterranean and may be much more widespread than currently believed.

The report is based on the first results of the study "The History of the Evangelical Christians-Baptists in Ukraine", carried out in 1994-1996 by the joint efforts of the Department of Religious Studies at the Institute of Philosophy of the National Academy of Sciences of Ukraine and the Odessa Theological Seminary of Evangelical Christian Baptists. A large-scale description and research of archival sources on the history of evangelical movements in our country gave the first experience of fruitful cooperation between secular and church researchers.

Large-scale tidal power development in the Bay of Fundy has been given serious consideration for over 60 years. There has been a long history of productive interaction between environmental scientists and engineers durinn the many feasibility studies undertaken. Up until recently, tidal power proposals were dropped on economic grounds. However, large-scale development in the upper reaches of the Bay of Fundy now appears to be economically viable and a pre-commitment design program is highly likely in the near future. A large number of basic scientific research studies have been and are being conducted by government and university scientists. Likely environmental impacts have been examined by scientists and engineers together in a preliminary fashion on several occasions. A full environmental assessment will be conducted before a final decision is made and the results will definately influence the outcome.

Edge computing is the next Internet frontier that will leverage computing resources located near users, sensors, and data stores to provide more responsive services. Therefore, it is envisioned that a large-scale, geographically dispersed, and resource-rich distributed system will emerge and play a key role in the future Internet. However, given the loosely coupled nature of such complex systems, their operational conditions are expected to change significantly over time. In this context, the performance characteristics of such systems will need to be captured rapidly, which is referred to as performance benchmarking, for application deployment, resource orchestration, and adaptive decision-making. Edge performance benchmarking is a nascent research avenue that has started gaining momentum over the past five years. This article first reviews articles published over the past three decades to trace the history of performance benchmarking from tightly coupled to loosely coupled systems. It then systematically classifies previous research to identify the system under test, techniques analyzed, and benchmark runtime in edge performance benchmarking.
